Patent JP-H01136586-A (JP)
Title: Dc power unit
Inventor: SATO KOZO
IPC: H02H7/20
Filed: 1987-11-19
Abstract: PURPOSE:To suppress overcurrent, by performing control such that the switching period of a noncontact switching element is lengthened based on a comparison result between a detected voltage of a load current detection circuit and a reference voltage and performing regulation such that the impedance of an impedance circuit increases. CONSTITUTION:When overcurrent flows through a brushless motor 1, level of voltage Vd detected through a load current detecting circuit 17 increases. When a difference between the detected voltage Vd and a reference voltage Vs fed from a current setting circuit 13 exceeds over a preset limit level, a control circuit 3 performs control such that the output period of ON command signals S1, S2 from transistors 11, 12 is lengthened so as to increase the impedance of an impedance circuit 4. Consequently, output voltage Vout from the impedance circuit 4 drops to decrease load current flowing through the impedance 4.

Title: Method and apparatus for efficient compression of high-quality digital audio
Inventor: SUBURAMANIAASU DARUSANAN
IPC: G10L19/00
Filed: 1994-11-28
Abstract: PURPOSE: To provide a method and system by which digital audio signals containing a plurality of samples can be compressed efficiently. CONSTITUTION: Each sample is divided into a plurality of subbands. The signal- mask ratio(SMR) of each subband is predicted by utilizing a model indicating the relationship between the energy value and the SMR value based on a prescribed acoustic psychological model. A certain number of bits is allocated in accordance with the predicted SMR and a preselected bit rate. Thereafter, each subband is quantized, based on the allocated number of bits. Therefore, digital audio signals can be compressed efficiently at a high speed, because the number of instruction cycles is remarkably reduced as compared with the processing using a PM1 or PM2 in a standard DSP environment.

Abstract: PURPOSE:To effectively reduce any switching sound provided by a connection switching mechanism by connecting parts of a plurality of heat source side heat exchangers to an evaporator and the others of the heat exchangers to a condenser, and thereafter switching the cycle of utilization side heat exchangers. CONSTITUTION:A gas pipe of a utilization side heat exchanger 5 is switched by a room connection switching mechanism 35 so as to be selectively communicated with a high pressure gas line 31 and a low pressure gas line 32.

IPC: C12Q1/686
Filed: 1989-11-10
Abstract: The invention relates to the direct detection of human papillomavirus DNA. The recently developed polymerase chain reaction has been modified in order to improve sensitivity and specificity. It is possible, by choosing suitable oligonucleotide primers (amplimers) and reaction temperatures, for individual HPV genes to be identified among the total cell 4 DNA and amplified to such an extent that non-isotopic detection is possible. In addition, the use of reverse transcription allows deliberate amplification of spliced mRNA and thus an indication of premalignant or malignant states or lesions.
